Materials
Austenitic Manganese Steels:
- Tough
- Crack resistant
- Soft
- Ability to work-harden
Martensitic and High Speed Steels:
- High stress, heavy impact
- Tough
- Good combination of abrasion and impact resistance
- Abrasion resistance that increases with carbon and chromium content at the expense of impact resistance
Nickel- and Cobalt-Based Alloys:
- Non-lubricated metal-to-metal wear
- Wear resistance
- Corrosion resistance
- Heat resistance
- Good all-around strength
- Low ductility
Martensitic and High-Chromium Iron:
- Abrasive conditions accompanied by high temperature and/or corrosion
- Excellent resistance to wear by most materials
- Brittle
Tungsten Carbide Deposits:
- Extreme resistance to sliding abrasion by hard minerals
- Worn surfaces become rough
- Extremely abrasive conditions where extra cost is warranted
